This reverts commit 2a58b4a39a, reversing
changes made to dd63169077.
After patch 87c8d63b7a,
table_resharding_compaction_task_impl::run() performs the forbidden
action of copying a lw_shared_ptr (_owned_ranges_ptr) on a remote shard,
which is a data race that can cause a use-after-free, typically manifesting
as allocator corruption.
Note: before the bad patch, this was avoided by copying the _contents_ of the
lw_shared_ptr into a new, local lw_shared_ptr.
